Checking The Float Level (Float Height); Draining The Float Chamber Of The Carburetor; Oil Circuit - HUSABERG Edition 2004 Owner's Manual

MAINTENANCE WORK ON CHASSIS AND ENGINE

CHECKING THE FLOAT LEVEL (FLOAT HEIGHT) *

For this purpose, dismount the carburetor and remove the float
chamber. Hold the carburetor in a slanted position such that the
float will abut the float needle valve but not compress it.
In this position, the edge of the float should be parallel with the
float chamber sealing surface (see illustration).
If the float height does not correspond to the desired value, check
the float needle valve and, if necessary, replace it.
If the float needle valve is o.k., you can adjust the float height by
bending the float lever (1).
Mount the float chamber, install the carburetor, and adjust the idle
speed.

DRAINING THE FLOAT CHAMBER OF THE CARBURETOR *

Following every wet cleaning procedure, the float chamber of the
carburetor should be drained in order to remove any water that
may have penetrated into it. Water in the float chamber causes
engine malfunction.
Perform this task on a cold engine. Close the fuel tap, and place a
cloth underneath the carburetor, which is able to absorb any esca-
ping fuel. Unscrew the plug (2), and clean it with compressed air.
Then, mount the plug together with its gasket, open the fuel tap,
and check the float chamber for any leaks.
NOTE: Fuel is easily flammable and toxic. When handling
fuel, be sure to exercise the utmost caution. Never per-
form any work on the fuel system near open flames or
burning cigarettes.
Always allow the engine to cool off first. Immediately
clean up any fuel which may have been spilled. Materials
saturated with fuel are also easily flammable. In case you
ingested fuel or
consult a doctor immediately.
Dispose of the fuel properly.

OIL CIRCUIT

The oil pump (3) draws the engine oil from the oil sump through
the oil screen (4) and pumps it past the pressure relief valve (5) to
the oil filter (6). It continues to the crankshaft (7), partly branching
off through a hole to lubricate and cool the piston (8) and the
piston pin bearing. Once through the crankshaft, the engine oil is
pumped to the conrod bearing (9) and branches off again to the
bearings in the balance weight (10).
The camshaft (11) is lubricated by the engine oil which is transpor-
ted to the cylinder head by the timing chain (12).
On the downward movement of the piston, engine oil is pressed
from the crankcase through the diaphragm valve (not depicted) to
the transmission and shift mechanism.
